Patented June 11, 1907 A plication fil d August 16, 1905. Serial No. 274.367.

To rrZZ whom it may concern:

Be it known that I, WILLIAM H. DODGE, a citizen of the United States, and a resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Covers or Caps for Jars, Cans, Bottles, &c., of which the following is a specification.

This invention relates to covers or caps for bottles, jars, cans or other vessels, whether made of glass, tin or other material.

It is especially adapted for sealing the tops to tin cans, such for instance as spice or baking powder cans. It may also be used for hermetically sealing the tops on to cans containing fruit, preserves, jams, and food products of all kinds, as well as cereals, vegetables, etc.

The object of the invention is to reduce the cost of such covers or caps, and furnish a means of closing or sealing such jars, cans or other vessels, quickly and cheaply; and moreover to produce such a cap or cover as can not only be put on quickly, but so that it can be removed quickly without injury to the can or jar or their contents. This I accomplish in the manner described and by means of the construction shown in the drawings accompanying this description, in which Figure 1 is a view of the sheet metal blank from which my cover is made. Fig. 2 is the blank as formed, ready to be closed. Fig. 3 is a top view of the cover when placed on the jar, can or bottle. Fig. 4 is a vertical section of a bottle with cover fastened on by being turned under an annular head around the neck of a bottle. Figs. 5 and 6 are similar vertical sectional views of the cap or cover, when put on an ordinary jam jar or baking powder can Fig. 5 showing the cap not fully on. Figs. 7, 8 and 9 are different views of the locking device.

Similar reference marks refer to similar parts throughout the several drawings.

In Figs. 1, 2, 3 and 4 the numeral 1 refers to the top-plate of the cap or cover, which topplate is forced down on to a compressible lining or packing 2, of paper, rubber or cloth, shown in Figs. 4, 5, and 6.

At 3 and 3 in Figs. 2, 5 and 6 I show that part of the cover or cap called the movable locking bands. These bands are shown in Fig. 1 in blank, and are turned down with the other part 4 which forms the fixed part of the complete band. The part shaded (5 Fig. 1) is cut out of the blank, and then or projection the cover looking down on its top, (the entire band or downwardly pending edge 3, 3 and 4 being turned down) has the appearance shown in Fig. 2. The horizontal inwardly projecting edges, 6 and 6 being left as a part of the movable bands 3 and 3 when the shaded part 5 is punched out.

It will be observed that each of the bands, 3, 3, is integrally connected at one end with the adjacent fixed part 4, while the other, and proximate ends of said bands, 3, 3, are free, the locking devices, hereinafter described, are formed in these free ends of said bands.

In one of the ends of the movable band in the lower edge thereof, as shown at 7 Fig. 7, I have a locking slot, and in the other end, or in the part 3, I have a tongue 8. This tongue is formed by punching out a portion of the material of the band at a point intermediate the upper and lower edges thereof. After the shaded part 5 is punched out, the movable ends of the part 3 and the part 3 (as shown in Fig. 2) are brought together and looked as shown in Figs. 8 and 9, and the cap or cover on top has the appearance shown in Fig. 3. The horizontal inwardly projecting flanges 6 and 6, thus overlap substantially one half of top plate 1, around the edge 9 (Fig. 2) as shown by the dotted line in Fig. 3.

The movable bands 3 and 3 are made to bend laterally at where they join the fixed band 4, or at the points 10 and 10 in Fig. 2. In Fig. 4 the compressible packing 2 is represented by a piece of soft, thick and compressible paper; but in Figs. 5 and 6 this packing is represented as a piece of cloth, which I dip in paraffin, wax or some other suitable material in liquid state. It is then laid snugly over the top of the jar or can shown in Figs. 4 and 6, or other receptacle and the cap or cover; the movable bands 3 and 3 locked together as shown in Figs.9 and 3, is then forced tightly over the top of such jar or can, as shown in Figs. 5and 6. This cover or cap, thus put on, hermetically seals the jar or can; and it may be instantly removed .by bending back the tongue 8 (see Figs. 8 and 9) which unlocks the movable bands 3 and 3 so that they may be laterally moved outwardly at the ends as shown in Fig. 2. This is one of the special features of my inventionthe ease with which the cap or cover may be removed from the jar, can or bottle.

In Fig. 4 is shown how my cap or cover may be adapted for use on bottles or jars which have a projecting annular bead or shoulder 13, around the mouth or neck. l The lower edges of the depending bands 4 and 3 and 3, at 14, Fig. 4, (after the said movable bands 3 and 3 are locked together as shown in Figs. 9 and 3), are turned or spun under the shoulder or bead 13, thus firmly holding down the cap onto the compressible paper packing 2. The horizontal inwardly projecting flanges 6 and 6 of the movable bands 3 and 3 it"will be noticed over-lap the periphery 9 (see Fig. 2) of the 1 top-plate 1, substantially half way around the cap (shown more clearly inFig. 4), so that the packing forms a tight joint on top of the edges of the bottle or jar around the mouth or neck.

Some of the special features of my inven tion are, that the cap is made from one piece of sheet metal; that it is equally adapted for hermetically sealing bottles, jars, etc. which have a projectin shoulder or bead around the mouth or neck, or for use on bottles or jars without such bead or shoulder; or it can be used on ordinary baking powder cans, or spice cans, of metal, glass or wood; or metal pails such as butter and lard pails, or any other kind of cans or pails whether made with rim, or straight or wire edge, and whether round, square, octagon or oval. Another special feature of my invention is that the two movable bands 3 and 3, are made each bendable laterally at their outer ends, and are lockable together or unlockable at each of their inner ends, which inner ends are movable outwardl y laterally. Another special feature of my invention is the locking device for locking together the laterally movable ends of the two parts of the downwardly depending band, as shown in Figs. 7 and 9. The end 3 is easily raised or lowered, so that the tongue 8 engages the slot 7, and the parts of the band are easily and securely locked or unlocked. My cap or cover is also made from one piece of metal.

I am aware that caps or closures have been made for jars or bottles having an annular projection around the neck, from one piece of metal; but so far as I know once put on they are all with great difficulty removed, with exception of my cap or closure described in my application for patent, Serial No. 246,385, filed Feby. 20, 1905. This invention is in some respects an improvement on the above invention (No. 246,385) for this has an improved locking device, and the laterally movable part of the locking band is in I two parts or wings locked together, so that the ends of the bands 3 and 3, once being unlocked, the cap is the more readily disengaged from the bottle or jar. In this invention, also, the cap or cover is well adapted for cans, jars or bottles without the aforesaid annular projection, on account of the facility with which the ends of the laterally movable parts 3 and 3 are unlocked by the locking device shown in Fig. 9, as hereinbefore described.

The cap or cover is shown on a can in Fig. 6, and in Fig. 5 it is shown part way on a jam jar, neither of which have the annular projection referred to.

Having thus described my invention what I claim as new and original and desire to secure by Letters Patent, is 1-- 1. A cap or cover for bottles, jars, cans, etc., made in one piece and having a top plate and a depending locking band, formed integrally with each other, said band being separated from the top plate substantially one half its circumferential length, the sepa-' rated part of the band having an. inwardly projecting lip, said separated part and its lip being severed or divided at a point intermediate their length to form free movable ends, one of said movable ends having a tongue formed therein and the other having a slot extending transversely partway across the same from one edge thereof and adapted to receive said tongue to lock said ends together.

2. A cap or cover for bottles, jars, cans, etc., made in one piece and having a top plate and a depending locking band formed integrally with each other, said band being separated from the top plate substantially one half its circumferential length, the separated. part of the band having an inwardly projecting lip, said separated part and its lip being severed or divided at a point intermediate their length to form free movable ends, one of said movable ends having a tongue punched out of the same intermediate the edges thereof, and the other movable end having a slot extending transversely part way across the same from the lower edge thereof and adapted to engage over the said tongue to form a lock for said ends.
